Discover what lies beneath your lawn

It is one of the world’s most precious natural resources and is vital for growing the food that we depend on for survival.

But how much do you know about the soils beneath your feet and the creatures that make their home there?

As milder temperatures begin to arrive, it’s the perfect time to discover the world beneath your lawn by taking part in the OPAL soil and earthworm survey.
